IMPROVEMENT I'N MACHINES FOR WlND-INGCONHCAL BBEINS.

Specilcation forming part of Letters Patent No. 49,582, dated August 22, 1865.

Llo ali whom'z't may concern:

Be it known that I, GEORGE S. BRADFORD, e in the county of Bennington and State of Vermont, have invented certain new and useful Improvements in Machines for Winding Conica'l Bobbins, ot' which the followingis a lull and exact description, reference beinghad tothe annexed drawings, in which-,-

Figure l is a side view, and Fig. 2 a partial front elevation, of a machine embodying my invention g Figs. 3 and 4, partial sections of a like machine at or nearl the line z z in Figs. 2, `5, and 6; Fig. 5 a plan,'Fig. 6 afront elevation, and` Fig. 7 a section at the line y y in Figs. 5 and 6, of a portion. of the saine machine; and of another part letters in all the figures, and the directions in i which the parts move being indicated by arrows gthereon. i Myinventionrelatestothatclassot'machines `for winding yarn on conical bobhins in which the'conical part of thebobbin or thefyarn` wound thereon is turned in contact with and pressed endwise' by Aa yielding force toward or against a conical roller, so as to therebyrevolve the latter and be pressed back endwise by the accumulation ot' yarn on the bobbin as the winding progresses; and one part of my invention consists in revolving the'conical bobbin with its axis in a prostrate, horizontal, or nearly horizontal position hymeans ot a bobbinspindlewhich is revolved hy and with a rotary sleeve or collar thereon, and pressed endwise within the said rotary`sleev'e or collar'and toward the conical roller by means ot a weighted lever or its equivalent, substantially as shown by the annexed drawings, whereinA is the conical bobbin, B the bobbin-spindle, O the rotary sleeve or collar,D the conical roller, and E the weigh ted lever.

With my aforesaid improvement, the gradually-increasing weight of yarn on the bobbin a's' the Winding progresses does not injuriously` lessen the power of the deviceby which the bobbin-spindle or bobbin is pressed endwise toward or against the conical roller, as such increasing weight of yarnI would do if the bobbin and hobbin-spindle werearranged with their common axisverticahor nearly so, and pressed upwardatowardor against a conical roller by a weighted lever or its equivalent, as in some bohbin-winders heretofore devised; and with my aforesaid improvement the bobbin is pressed endwise toward or against the conical roller by a forccgvhich is not liable to be'either increased or'lessened injuriously by any variation in the width, or thickness,or flexibility, or tightness of the beltnor band by which the sleeve or collar and bobbin-spindle are revolved, it would heitthe bobbin-spindlc was revolved and also pressed endwise horizontally toward the conical roller by a quartertwist belt ruiming over a long pulley tast on the bobbin-spindle, asin some bobbin-winders heretofore used, wherein the said quarter-twist belts, even when ot'I uniform `width and thickness, areliahle to press the bohbinsagainst the conical rollers With either too great or toolittle force at different limes, according to the temporary tightness or looseness with which the belts run,- which conditions of tightness and -lo'oseness are enernll suh'ect to 0rent variations, not only from the ordinary wearing and mechanical stretching of the belts in use,` but also from the shrnking'and stretching ot the belts nnde changes in the temperature and moisture ofthe atmosphere to which the belts are exposed.

Another part ot' my invention consists in mounting the conical roller on a pivot, hinge, rock-shaft, or axis which is arranged in respect to the bobbin-spindle, and provided with a weighted lever or other suitable holding device in such a niannerthattheconical roller will be thereby supported and held stationary in a proper position to be pressed against by the conical part cfa bobbin on the spindle in winding,r yarn on the bobbin, and that Vthe conical roller can be turned bodily on or with the said pivot, hinge, axis, or rock-shaft as a center, entirely away from the bobbin on the bobbinspindle, so as to allowa wound hobbin to be freely taken endwiseoft' from and a naked bobbin pnt onto the bobbiu-spindle, and then turned bodily back again to the properstationary position to be pressed against and revolved by the bobbin on the bobbin-spindleinwinding yarn on the bobbin. Thus, for example,in the annexed drawings, F is the axis or rock-shaft, on which the conical roller D is mounted, and G a weighted lever, which is fastened to .the

shaft F,'and which, when resting on a station ary part of the machine, as at h in Figs. l and 2, then holds the conical roller in the proper stationary position to be pressed against by the conical part of the bobbin A or of the wound yarn X thereon, and which at the same time will allow the conical roller to be easily turned entirely away from the bobbin,'as indicated by the dotted lines win Figs. 1, 3, and 4. By thus mounting the conical roller on a pivot, hinge, or axis I the conical roller may also b e easilymade adjustable, so that it can be set and held in various directions in respect to the bobbinspindle lto it variously-tapered conical bobbinswhen put onto the'bobbin-spindle. As, for .eXan1ble, in the annexed drawings,'the Weighted lever G has a socket which fits on a round part of the shaft F, with a set-screw, z', Fig,l 5, so that the levercan be therebyfastened to the shaft in various angular directions in respect to the roller `D, and the latter consequently set in various directions in respect to the bobbin-spindle B when the weighted lever4 G rests on the same stationary part ofthe machine, as at h in'Figs. l and 3; and by thus mounting the conical roller on ahin ge, pivot, or rock-shaft the conical roller can also be made adjustable in various other ways of more or less practical importance, whatever may be the temporary Working direction. of the conical rollerin respect to the bobbin-spindle. Thus, in the annexed drawings, the roller D is made adjnstablein the direction of its axis ot' revolution by being made torevolve on a spindle, j, which has a shank, 1c, Fig. 3,\vhich extends through a socket in the shaft F, andisfastened in different positions therein by a set-screw, l, and the roller-Dis also made adjustable to different distances from and in a direction perpendicular, or nearly so, to the axis ofthe bobbinspindle, and also in adirection lengthwise and parallel, or nearly so, thereto, by having the bearings m on, Figs. 4 and 6, of; the shaft F movable in a vertical direction and fastened by clamp-screws n n, Figs. 6 and 7, to a stock, o, which is movable horizontally in thelengthwise direction ot' the bobbin-spindle and fastened to the frame-work F ofthe machine by clamp-screws q q, Figs. 3 and 5.y

In the annexed drawings, His the main driving-shaft, from which the bobbin-spindle is revolved by a belt or band, I, running around a pulley, R, fast on the shaft H, and over a fast pulley, i", on the sleeve C, which has also aloose pulley, s, Figs', 4, and 8, to and from which the 'band I is changed by a belt-shifter, J, to stop and start the rotation of the bobbinspindle.

Fig. 8 shows the rotary sleeve C, with an internal stud or feather, t, tting into a longitudinal groove, e, in the spindle B, to make the sleeve revolve the spindle as 'the latter is slid endwise. f

'K is a' yarn-carrier, which is vibrated so as to lay the thread of yarn properly on the cone of the revolving bobbin by a cam, L, fast oua pulley, M, vwhich is turned by a belt, N, from a pulley, S, fast on the driving-shaft H.

What I claim as my invention, and desire to s'ecureby Letters Patent, is-

41. The combination of a conical roller, D,

with a prostrate conical bobbin, A, and b obbin-spindle B,revolved`by a rotary sleeve or colla-r, C, and pressed eudivise toward the' said conical roller by a weighted lever, E, -or its equivalent, substantially as herein described.

2. Mounting the conical roller ou a pivot or axis, F, substantially as and for the purpose herein set forth.

GEORGE s. BRADFORD.
